Risk factors for attempted suicide in non-psychotic patients with suicidal ideation.

OBJECTIVE: In Eastern European countries, suicide rate are among the highest in the world and suicide attempts are among the most important risk factors. The aim of this study is to identify factors associated with suicide attempt (SA) in non-psychotic patients with suicidal ideation (SI). METHODS: Among 6204 consecutive adult patients (residents of Moscow) with non-psychotic mental disorders (NPMD), 361 individuals aged 18-77 years (median 24 years) were enrolled in the study after screening for lifetime SI with the Self-Injurious Thoughts and Behaviors Interview (SITBI). All participants were assessed for sociodemographic variables, psychiatric diagnosis, family history of mental disorders, history of abuse, sexual behavior, psychiatric treatments, suicide plan, SA, and nonsuicidal self-injury (NSSI). Results of multivariable analyses (MV) are presented as odds ratios (OR) with 95% confidence intervals (CI). RESULTS: 166 patients (46%) reported lifetime SA. In MV, variables associated with SA included smoking (OR 2.1; 95% CI 1.2-3.7), having made a suicide plan (OR 3.4; 95% CI 2.0-5.7), and scars covered by tattoos (OR 5.2; 95% CI 1.5-17.9). History of law violation (OR 2.0; 95% 1.0-4.2) was of borderline significance. CONCLUSIONS: Transition from SI to SA in patients with NPMD was associated with smoking, suicide planning, history of law violation and presence of tattoos covering scars.

Association of breastfeeding with mental disorders in mother and child: a systematic review and meta-analysis.

BACKGROUND: Breastfeeding has long been associated with numerous benefits for both mothers and infants. While some observational studies have explored the relationship between breastfeeding and mental health outcomes in mothers and children, a systematic review of the available evidence is lacking. The purpose of this study is to systematically evaluate the association between breastfeeding and mental health disorders in mothers and children. METHODS: We systematically searched MEDLINE and EMBASE from inception to June 2, 2023. The inclusion criteria consisted of all studies evaluating links between breastfeeding and development of mental health disorders in children and mothers. Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) while grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to assess the certainty of evidence. A random-effects meta-analysis was used if possible, to estimate the odds ratio for the association between breastfeeding and mental health outcomes. The Mantel-Haenszel method was utilised for pooling ORs across studies. Study heterogeneity was assessed using the I2 statistic. RESULTS: Our review identified twenty-one original study. Of these, 18 focused on the association between breastfeeding and child health, assessing depressive disorders, schizophrenia, anxiety disorders, eating disorders and borderline personality disorder. Three studies evaluated the associations between breastfeeding and maternal mental health disorders. Three studies looking at outcomes in children showed no significant association between breastfeeding and occurrence of schizophrenia later in life (OR 0.98; 95% CI 0.57-1.71; I2 = 29%). For depressive disorders (5 studies) and anxiety disorders (3 studies), we found conflicting evidence with some studies showing a small protective effect while others found no effect. The GRADE certainty for all these findings was very low due to multiple limitations. Three studies looking at association between breastfeeding and maternal mental health, were too heterogeneous to draw any firm conclusions. CONCLUSIONS: We found limited evidence to support a protective association between breastfeeding and the development of mental health disorders in children later in life. The data regarding the association between breastfeeding and maternal mental health beyond the postnatal period is also limited. The methodological limitations of the published literature prevent definitive conclusions, and further research is needed to better understand the relationship between breastfeeding and mental health in mothers and children.

Factors Associated with Non-Binary Gender Identity in Psychiatric Inpatients with Suicidal Ideation Assigned Female at Birth: A Case-Control Study.

The study aimed to investigate factors associated with non-binary gender identity in Russian female psychiatric inpatients with suicidal ideation. This case-control study included 38 female inpatients with non-binary gender identity and a control group-76 cisgender women matched for age (age range 19-35 years, M age, 21.5 years); both groups were psychiatric inpatients with suicidal thoughts. All patients underwent the Self-Injurious Thoughts and Behaviors Interview and completed the brief Reasons for Living Inventory. We also used the WHO Quality of Life Questionnaire (WHOQOL-100) and the Life Style Index (LSI). Non-binary gender identity in inpatients with suicidal ideation was associated with lower educational level, higher unemployment rate, being more socially reticent in preschool, and lifetime sexual experience with both male and female partners. In addition, they were younger at the time of the first suicidal ideation, suicide plan development, and attempt. Non-binary inpatients had lower scores in freedom, physical safety, and security facets of WHOQOL-100 and a higher level of intellectualization on LSI. People with non-binary gender identity face educational, employment, and communication issues. They also have distinct suicidal thoughts and behavioral profiles. These issues and differences mean unique approaches to suicide prevention for a population of inpatients with non-binary gender identity are needed.

Non-Suicidal Self-Injury in Russian Patients with Suicidal Ideation.

BACKGROUND: Nonsuicidal self-injury (NSSI) is recognized as a public health concern for its association with unfavorable outcomes, including suicidal behavior. The aim of this study is to identify factors associated with NSSI among patients with nonpsychotic mental disorders (NPMD) and suicidal ideation in Russia. METHODS: A retrospective cohort study was conducted in the Moscow Research and Clinical Center for Neuropsychiatry between November 2017 and May 2019. The sample was composed of consecutive patients with lifetime suicidal ideation (from the Self-Injurious Thoughts and Behavior Interview) seen in the center's psychiatric ward for NPMD. The patients were divided into two groups: those with and without lifetime NSSI. Sociodemographic variables, psychiatric diagnosis, family history of mental disorders, history of physical or sexual abuse, sexual behavior, ad-hoc psychiatric treatments, suicidal ideation, plans, and gestures or attempts were investigated. RESULTS: Six thousand, two hundred and four consecutive patients were screened for suicidal ideation. Out of a total of 361 patients (87.3% females) with suicidal ideation, 217 (60.1%) reported NSSI. Variables independently associated with NSSI included age <25 years (OR 6.0, CI 2.5-14.7), dissatisfaction with the perceived parenting style (OR 3.3, CI 1.5-7.4), bullying (OR 2.6, CI 1.0-6.5), severe body modifications (OR 11.9, CI 1.1-134.3), experience with illicit drugs (OR 4.4, CI 1.9-10.3), and eating disorders (OR 4.9, CI 2.0-11.8). LIMITATIONS: Retrospective design, referral population, single center study, and exclusion of psychotic patients. CONCLUSIONS: NSSI is associated with age <25 years old, dissatisfaction with perceived parenting style, bullying, severe body modifications, lifetime experience of illicit drug-use, and lifetime eating disorders.HIGHLIGHTSNonsuicidal self-injury is a significant public health concern for its association with suicidal behavior.60.1% of Russian patients with non-psychotic mental disorders (NPMD) and suicidal ideation reported lifetime NSSI.NSSI in Russian patients with NPMD and suicidal ideation is associated with age less than 25 years, dissatisfaction with perceived parenting style, bullying, severe body modifications, lifetime experience of illicit drug use, and lifetime eating disorders.

Validation of the Generalized Anxiety Disorder-7 (GAD-7) in Russian people with epilepsy.

OBJECTIVE: To assess the capacity of Generalized Anxiety Disorder-7 (GAD-7) to detect anxiety disorders in a Russian sample of patients with epilepsy and to validate this instrument for rapid screening of anxiety in these patients. METHODS: Study included 233 patients with epilepsy, both inpatients and outpatients. For all patients Mini-International Neuropsychiatric Interview was conducted as a gold standard for diagnosis of mental disorders. All patients also completed the questionnaires - the Russian version of GAD-7 and Hospital Anxiety and Depression Scale (HADS) to assess convergent validity. Chi-square and Fisher's exact tests were used to compare categorical variables, and the Mann-Whitney test was used for the quantitative ones. Internal consistency was assessed using Cronbach's alpha, Cronbach's alpha at point deletion, and corrected point-to-point correlation. ROC analysis was used to evaluate the properties of the GAD-7 to determine anxiety disorders. RESULTS: Among 97 (41.6%) patients with epilepsy diagnosed with any anxiety disorders, 42 (18%) had panic disorder, 37 (15.9%) had agoraphobia, 17 (7.3%) had social anxiety disorder, and 64 (27.5%) had generalized anxiety disorder; 42 patients (18%) showed a combination of several anxiety disorders. The overall GAD-7 score was similar to other epilepsy studies, but higher cutoff scores characterize our sample. The scale performed well in detecting any anxiety disorder with the AUC of 0.866 and the optimal cutoff point > 8 points, and in detecting GAD with AUC = 0.922 and the optimal cutoff point > 9 points, showing overall acceptable sensitivity. CONCLUSION: Russian version of the GAD-7 could be used as a screening tool for any anxiety disorders in PWE with the optimal cutoff score > 8 points.

Effect of agomelatine 25-50 mg on functional outcomes in patients with major depressive disorder.

PURPOSE: The purpose of this work is to investigate the effect of agomelatine on functioning compared with placebo in patients suffering from Major Depressive Disorder (MDD). METHODS: Data from two randomized, parallel, double-blind, placebo-controlled short-term agomelatine trials conducted by the manufacturer, one in adult and one in older patients, that evaluated the effect on social functioning, were pooled. The short term effect of agomelatine on social functioning was assessed using the Sheehan Disability Scale (SDS), according to SDS total and sub-item scores, as well as on functional response and remission rates. The Hamilton Depression rating scale was used to quantify severity of depression symptoms. A meta-analytic method using a random effect model was used to assess differences in treatment. RESULTS: In total, 633 patients (422 on agomelatine; 211 on placebo) were included in the analyses. At endpoint, there was a significant difference in favor of agomelatine vs placebo of 3.47 (0.62) (95% confidence interval: [2.26; 4.67]; P < 0.001) on the SDS total score. Rates of symptomatic response and remission according to HAM-D17 total score were significantly higher in patients taking agomelatine (54.3% and 18.3% respectively) than in those taking placebo (29.4% and 9.5% respectively) with respective differences of 24.9%, p < 0.001 and 9.3%, p < 0.001. The functional response rates were 52.9% on agomelatine and 34.5% on placebo, with a significant placebo-agomelatine difference in favor of agomelatine of 18.30 ±â€¯4.39% (95% CI: [9.69; 26.91], p < 0.001). The functional remission rates were 22.3% with agomelatine and 10.2% with placebo, with a significant difference in favor of agomelatine of 11.7 ±â€¯3.11% (95% CI: [5.61; 17.79], p < 0.001). Combined symptomatic and functional response rates were 42.1% on agomelatine and 23.2% on placebo (p < 0.001), and the combined symptomatic and functional remission rates were 13.9% on agomelatine and 6.8% on placebo (p < 0.005). CONCLUSION: This study confirms the efficacy of agomelatine in improving social functioning in MDD patients.

Efficacy and safety of agomelatine (10 or 25 mg/day) in non-depressed out-patients with generalized anxiety disorder: A 12-week, double-blind, placebo-controlled study.

Agomelatine is efficacious in reducing symptoms and preventing relapse in placebo-controlled trials in generalised anxiety disorder (GAD). Nevertheless, fixed dose studies of agomelatine in GAD have not been undertaken. To determine the minimally effective optimal dose of agomelatine in GAD, the efficacy of two doses of agomelatine (10 and 25mg/day) was investigated in a 12-week, placebo-controlled, double-blind, international study in patients with a primary diagnosis of GAD. The primary outcome measure was the Hamilton Anxiety scale (HAM-A). The study was undertaken in 35 clinical centers in Finland, Russia, Poland, Slovakia and Ukraine from August 2013 to January 2015. 131 out-patients were included in the agomelatine 10mg group, 139 in the agomelatine 25mg group, and 142 in the placebo group. Both doses of agomelatine were associated with significant decreases in the HAM-A at week 12 (difference versus placebo of 7.16±1.00 at 10mg and 11.08±0.98 at 25mg, p<0.0001). Significant effects on all secondary measures were found for both doses at week 12; including psychic and somatic HAM-A subscales, response rate, remission on the HAM-A, and functional impairment. Findings were confirmed in subsets of more severely ill patients on all endpoints. The low placebo response rate observed in this study was consistent with an increase in the quality of data collected. Agomelatine was well-tolerated by patients, with minimal distinctions from placebo. There was a dose effect of agomelatine, with a greater placebo-agomelatine difference in the agomelatine 25mg group, compared to the agomelatine 10mg group.The present data support early work indicating the efficacy and tolerability of agomelatine in the treatment of GAD.

Sustained efficacy of agomelatine 10 mg, 25 mg, and 25-50 mg on depressive symptoms and functional outcomes in patients with major depressive disorder. A placebo-controlled study over 6 months.

This randomized placebo-controlled "dose relation study" was conducted in patients who met criteria for major depressive disorder, to evaluate the efficacy and safety of agomelatine during 24 weeks at 3 doses (i) low fixed dosage (10 mg/day, n=100 patients entered the extension period), (ii) fixed dosage (25 mg/day, n=111) and (iii) a flexible dosage with up-titration in case of insufficient improvement at week 2 (25-50 mg/day, n=115) versus placebo (n=85). Mood was evaluated using the Hamilton rating scale for depression (HAM-D17) and Clinical Global Impression (CGI) scale. The functional status was examined with the Sheehan Disability Scale (SDS). At last post-baseline assessment, there were significant placebo-agomelatine differences on mean HAM-D17 total scores in favour of each agomelatine dose regimen (4.51±1.06 points, p<0.0001 at 10 mg; 7.74±1.05 points, p<0.0001 at 25 mg and 7.72±1.05 points, p<0.0001 at 25-50 mg). The response rate according to HAM-D17 was significantly higher in patients taking agomelatine than those taking placebo (difference of 21.8% at 10mg p<0.001; 36.4% and 35.4% respectively at 25 mg and 25-50 mg, p<0.0001). The remitter rate was significantly higher in patients taking agomelatine than those taking placebo (difference of 16.7% at 10 mg p=0.003; 33.8% and 35.4% respectively at 25 mg and 25-50 mg, p<0.0001). The effects of agomelatine were corroborated by CGI scores. Agomelatine improved symptom-related functional impairment on all domains of the SDS scale for the fixed dose 25 mg, and the one step titration 25-50 mg dose regimen. Similar findings were obtained for all measures in the subgroup of severely depressed patients. All dose regimens of agomelatine were well tolerated and no unexpected adverse event was reported. Long term agomelatine treatment improves both mood symptoms and social and occupational functioning of moderately to severely depressed patients. There is a dose effect between 10 mg and higher dose regimens of agomelatine. The threshold dose of 25 mg for initiating treatment can be maintained over 6 months in depressed patients.

A placebo-controlled study of three agomelatine dose regimens (10 mg, 25 mg, 25-50 mg) in patients with major depressive disorder.

A randomised placebo-controlled "dose relation study" was conducted in 549 patients who met the criteria for major depressive disorder, to evaluate the efficacy and safety of three doses regimens of agomelatine during 6 weeks: low fixed dosage (10 mg/day, n=133), fixed dosage (25 mg/day, n=138) and a flexible dosage with up-titration in case of insufficient improvement at week 2 (25-50 mg/day, n=137). At last post-baseline assessment, there were significant and incremental placebo-agomelatine differences on mean HAM-D17 total scores in favour of each agomelatine dose regimen (2.46 ± 0.76 points, p=0.001 at 10 mg; 4.71+0.75 points, p<0.0001 at 25 mg and 4.92 ± 0.76 points, p<0.0001 at 25-50 mg) with statistically significant differences between 25 mg and 25-50 mg dose regimens compared to the 10 mg dose. The response rate according to HAM-D17 was significantly higher in patients taking agomelatine than those taking placebo (difference of 16.1% at 10 mg p=0.005; 25.9% and 27.4% respectively at 25 mg and 25-50 mg, p<0.0001). The benefit of agomelatine was demonstrated in the subgroup of severely depressed patients in the 25 mg and 25-50 mg/day regimens. Consistent clinical response according to CGI variables and better social functioning were found in patients receiving agomelatine. All dose regimens of agomelatine were well tolerated and no unexpected adverse event was reported. This study provides evidence of a dose effect for agomelatine between 10 mg and the therapeutic dose regimen of agomelatine 25-50 mg: the efficacy of the higher dose regimens being more efficacious than the lowest (10 mg) daily dose. The data support a definitive statement regarding the utility of 25 mg as the threshold dose for initiating agomelatine in depressed patients.

Agomelatine in generalized anxiety disorder: an active comparator and placebo-controlled study.

BACKGROUND: Agomelatine was efficacious in reducing symptoms in a short-term placebo-controlled trial in generalized anxiety disorder (GAD) and in preventing relapse in a longer term placebo-controlled study. An additional short-term placebo-controlled study is required by regulatory agencies to confirm the efficacy of agomelatine in GAD. METHOD: This 12-week, placebo-controlled, double-blind, randomized, parallel group, international, multicenter study was designed to confirm the efficacy of agomelatine 25-50 mg/d in the treatment of patients with a primary DSM-IV-TR diagnosis of GAD. The primary outcome measure was the Hamilton Anxiety Rating Scale (HARS) total score. Assay sensitivity was evaluated by including an escitalopram (10-20 mg/d) group. SETTINGS: The study was undertaken in 45 clinical centers in Argentina, Czech Republic, Finland, South Korea, Poland, Russia, and Slovakia from April 2010 to July 2011. RESULTS: One hundred thirty-nine outpatients were included in the agomelatine group, 131 in the placebo group, and 142 in the escitalopram group. Agomelatine significantly reduced mean (SD) HARS total score (agomelatine-placebo difference: 4.71 [1.03], P <.0001) and had significant effects on secondary outcome measures, including psychic and somatic HARS subscales, response rate (estimate [standard error]) (agomelatine-placebo difference: 27.4% [5.9%], P< .0001), remission on the HARS (agomelatine-placebo difference: 16.8% [5.4%], P = .002), Clinical Global Impressions-Severity of Illness scale (CGI-S) (P < .001), functional impairment (P < .0001), and sleep quality (P < .001). Findings were confirmed in the subset of more severely ill patients (HARS total score ≥ 25 with or without CGI-S ≥ 5 at baseline). Agomelatine was well tolerated by patients, with no more adverse events than placebo. Escitalopram was similarly efficacious but was accompanied by a higher incidence of adverse events compared to placebo. CONCLUSIONS: In clinical practice, agomelatine has at least similar efficacy to that of escitalopram for the short-term treatment of GAD and is well tolerated.

Effect of milnacipran on suicidality in patients with mild to moderate depressive disorder.

The presence of suicidal manifestations (thoughts and behavior) was studied in a cohort of 30 patients with mild to moderate depression during a 6-week treatment with the serotonin-norepinephrine reuptake inhibitor, milnacipran. At baseline mild suicidal thoughts were present in 46.7% of patients, the mean Hamilton Depression Rating Score (HDRS(17)) was 23.9 +/- 1.8 and the mean suicidality score on the Beck Scale for Suicidal Ideation (BSS) was 4.9 +/- 4.9. Suicidal thoughts decreased progressively throughout the study in parallel with other depressive symptoms. At no time during treatment was there any indication of an increased suicidal risk. Notably, the items retardation and psychic anxiety on the HDRS(17) decreased in parallel. This may possibly explain the lack of any "activation syndrome", which is occasionally observed at the early stages of therapy with some antidepressants and may be linked to a temporary increase in suicidal ideation. To our knowledge this is the first detailed report of suicidality during treatment with milnacipran.

Activation of mGlu2/3 receptors as a new approach to treat schizophrenia: a randomized Phase 2 clinical trial.

Schizophrenia is a chronic, complex and heterogeneous mental disorder, with pathological features of disrupted neuronal excitability and plasticity within limbic structures of the brain. These pathological features manifest behaviorally as positive symptoms (including hallucinations, delusions and thought disorder), negative symptoms (such as social withdrawal, apathy and emotional blunting) and other psychopathological symptoms (such as psychomotor retardation, lack of insight, poor attention and impulse control). Altered glutamate neurotransmission has for decades been linked to schizophrenia, but all commonly prescribed antipsychotics act on dopamine receptors. LY404039 is a selective agonist for metabotropic glutamate 2/3 (mGlu2/3) receptors and has shown antipsychotic potential in animal studies. With data from rodents, we provide new evidence that mGlu2/3 receptor agonists work by a distinct mechanism different from that of olanzapine. To clinically test this mechanism, an oral prodrug of LY404039 (LY2140023) was evaluated in schizophrenic patients with olanzapine as an active control in a randomized, three-armed, double-blind, placebo-controlled study. Treatment with LY2140023, like treatment with olanzapine, was safe and well-tolerated; treated patients showed statistically significant improvements in both positive and negative symptoms of schizophrenia compared to placebo (P < 0.001 at week 4). Notably, patients treated with LY2140023 did not differ from placebo-treated patients with respect to prolactin elevation, extrapyramidal symptoms or weight gain. These data suggest that mGlu2/3 receptor agonists have antipsychotic properties and may provide a new alternative for the treatment of schizophrenia.
